Enhanced GNU Make - tracing, error reporting, debugging, profiling and more

Here we have patched GNU Make 4.3 sources to add improved error reporting, tracing, target listing, graph visualization, profiling, and more. It also contains a debugger. Branches remake-4-2, remake-4-1, remake-3-82, and remake-3-81 for patched GNU Make 4.2, 4.1, 3.82, and 3.81 respectively.

See the readthedocs guide for information, including remake features, and installation.

The wiki also has information, including links to videos, and information for developers.

remake's Issues

.gitignore should ignore .vscode directory

I was working on remake using vscode, which creates a .vscode directory. That should be added to .gitignore.

I tried to install remake on our linux machines, but it failed with the below error messages:

to compile must need libreadline6-dev

Under Ubuntu12.04 there is only remake+dbg0.2,so i must compile myself.
./configure will not report error，however make will report undefined reference.
It's easy to resolve this problem,install libreadline6-dev,it will install many .h,rerun ./configure,make,this time success.
By the way,remake is really good,thank you!

Tutorial Video #2 missing

I went to:

http://showmedo.com/videotutorials/video?name=linuxBernsteinMakeDebug1&fromSeriesID=40

to watch the tutorial videos and it appears tutorial video #2 is missing. Is this video still available? If so, where can I find it?

pre-built W32 version

Is it at all possible to get a pre-built version (i.e. the .exe file) of remake, preferably 3.82 as that is the version of the GNU Make I am using, for Windows 32 ?

I have had no luck building the source code.

Thanks
Bob Workman

Add "set editing" command

This is a gdb command but the trepanning debugger don't support mixed emacs/vi commands, but instead basically use GNU Readline undeneath so you set which variant you want.

Here is the help from bashdb:

set editing [on|off|emacs|vi] 

Readline editing of command lines 

See also: 

show editing 

@boretom You up for adding this command?

(In going over documenting remake I came across this.)

Documentation URL is broken

• It's impossible to navigate to documentation from the home page http://bashdb.sourceforge.net/remake/remake.html/. "GNU Make Debugger Documentation online" link leads to http://bashdb.sourceforge.net/remake/remake.html/index.html, which is the copy of a home page.

Actual documentation URL is http://bashdb.sourceforge.net/remake/remake.html/Sample-Sessions.html#Sample-Sessions, and I could only navigate there from Google.

• Showmedo link ("Short (14 minute) demo of introducing debugging Makefiles – part 1") is dead.
• "Screenshot of remake under DDD" link is dead.

remake should set REMAKEFLAGS (for -X and -x) and not MAKEFLAGS

From make-4.1/NEWS +102

====> Version 4.0 (09 Oct 2013)

• New variable: $(GNUMAKEFLAGS) will be parsed for make flags, just like
  MAKEFLAGS is. It can be set in the environment or the makefile, containing
  GNU make-specific flags to allow your makefile to be portable to other
  versions of make. Once this variable is parsed, GNU make will set it to the
  empty string so that flags will not be duplicated on recursion.

...

Behavior of MAKEFLAGS and MFLAGS is more rigorously defined. All simple
flags are grouped together in the first word of MAKEFLAGS. No options that
accept arguments appear in the first word. If no simple flags are present
MAKEFLAGS begins with a space. Flags with both short and long versions
always use the short versions in MAKEFLAGS. Flags are listed in
alphabetical order using ASCII ordering. MFLAGS never begins with "- ".

Given this, when -X or --debugger is parsed, that value should not be set in MAKEFLAGS or MFLAGS.

And as with issue #25, debugger commands, "step", "next", "finish" and "continue" would modify the REMAKEFLAGS environment variable.

"next" (step over) and "finish" (step out) and "continue) should not cause recursive make to stop

The debugger command, "step" should cause a recursive invocation of make to stop in the recursion. The debugger commands "next", "finish" and "continue" should not.

Gist https://gist.github.com/rocky/2bf8ee0000a1efd53929
has a sample Makefile that can be used to test this. Files that would probably change are step.h, next.h, continue.h, and finish.h in folder debugger/command/, Possibly the routine that sets up the GNUMAKEFLAGS environment variable could be common.

What I think is needed is to change "step", "next", "continue", "finish" to set GNUMAKEFLAGS to include "X" as appropriate.

Merge request for debianization

Hi. I updated and pushed the remake debian package to the debian repo:

https://tracker.debian.org/news/788381

I'm co-maintaining the package with Yaroslav. The corresponding git branches live in your repository, so could you please fast-forward your debian and master-dfsg branches to those from my fork:

https://github.com/dkogan/remake

I'd make a pull request, but those create ugly extra merge commits that I'd like to avoid (it does a 'git merge --no-ff').

Thanks

Feature: allow searching parent directory for a Makefile.

I think a cool feature to add is that if no Makefile appears in the current directory the parent directory is searched (using that directory as the cwd) and so on.

This is the way many other more modern tools work, e.g. git, pyenv.

Create debugger library

The static .h include thing in debugger/commands has always been a bit of a hack.

There should be a debugger library.

Also that makes it easier to ignore when GNU readline is not around in mimalist environments, and you still want to other features of remake.

GNU remake 4.3

In issue #40 @boretom reports:

regarding make 4.3: I did a diff and I'm up for the task - not like from 3.8 to 4 :) ... it may take a week or two. If you're ok with that timeline I would take on the task.

@boretom thanks, the project can wait a week or two.

Note that regarding make 4.3, I recently read in the news (and can't find it now) that Linus Torvalds has found a way to take advantange of the speedup that was proposed over a year ago in 4.3 to parallel builds. And with this, there can be something like a 10x speedup in building the Linux Kernel on multicore machines by using the --jobs option along with his customization in the kernel that recently went out.

As a result, the prioritiy of getting this done has increased.

Another (somewhat accidental) benefit of remake over GNU make is that since it is not in the critical path of a lot of things, OS's that have 4.2 (or 3.x) can also install remake and that gives them an easy way to instal a newer GNU make to try it out without impacting existing programs.

So I had planned on doing this, but I'd rather if someone else did. That way, there are two people in the world that may understand this. And in the end I know the code will get much much better. (See my comment make previously somewhere else about making a lot of mistakes).

However... painful experience has shown that the right way to do this is to make two new branches, make-4-3 with the GNU make source, and another branch from that remake-4-3. And then with the 'diff"s from make-4-2 HEAD to remake-4-2 HEAD, "rebase" them onto the remake-4-3 branch. In other words, do not build off of the exisiting remake-4-2 branch at HEAD.

In the last paragraph, I put "rebase" in quotes because I don't necessariliy mean using git rebase. For such largish changes that might be too difficult. Of course, It is a possibility if that helps, but again; I just don't think it will, but I could be wrong.

So shortly I will be creating the two branches to work off of, although I'll leave the work from the branch from remake-4-3 to a fully featured remake 4.3 up to you.

The remake >= 4.0 tags all have the non-remake manpage

The make.1 manpage file in the recent tags is from GNU Make, without the remake-specific functionality described

Rsync fails from behind firewall

I was trying to build remake from behind a corporate firewall. Our firewall blocks rsync connections but allows wget. As a result, I could not update the po/*.po files.

The translationproject.org site recommends using wget instead. I would like to modify maintMakefile to use wget so as to be more firewall friendly.

Build fails on gcc-10

Hi. The latest 4.3-dbg1.5 release doesn't build with gcc-10:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=957756

This report is for the previous release, but the issue is there in the latest release too. The problem is that remake is defining global variables in header files, which creates multiple symbols (one for each object built from a .c that #includes such a header), and those symbols clash. gcc-10 changed the default build flags, which trigger the failure. The legacy mode can be enabled with -fcommon or we can not define globals in headers. This is the first issue described in the porting guide:

https://gcc.gnu.org/gcc-10/porting_to.html

Thanks

Checking correctness for multi-target rules

Multiple targets can be specified in a single make rule. While they are written only once at such a place, the make software usually expands the specification into several rules with the same recipe so far.
But this does not happen with pattern rules:

…
Pattern rules may have more than one target. Unlike normal rules, this does not act as many different rules with the same prerequisites and recipe. If a pattern rule has multiple targets, make knows that the rule’s recipe is responsible for making all of the targets. The recipe is executed only once to make all the targets.
…

• This technical detail has got important consequences on the handling of dependencies for (parallel) software builds because of multiple output files by special commands.
• How do you think about details from previous development discussions?

Can a variant of the command “remake --targets” help to identify questionable multi-target rules?

Allow target name after `--tasks`

Right now remake --tasks lists doc comments for all targets. But suppose I just want the comment for a single target.

It would be nice if I could put the target name after --tasks. For example:

make --tasks check

Pull out debugger code and put in a library.

The static .h include thing in debugger/commands has always been a bit of a hack.

There should be a debugger library.

Also that makes it easier to ignore when GNU readline is not around in mimalist environments, and you still want to other features of remake.

Recursive Make Profiling

I'd like a way to combine the generated callgrind profiles into a single profile when using recursive make.

--verbosity usage (--help) message does not match behavior

According to the usage message:

  --verbosity[=LEVEL]         Set verbosity level. LEVEL may be "terse" "no-header" or
                          "full". The default is "full".

But LEVEL is actually required.

$ remake -C Somedir --verbosity
remake: option `--verbosity' requires an argument

$ remake --verbosity -C Somedir 
remake: Nothing to be done for 'Somedir'

The latter example demonstrates that --verbosity consumes the next argument as a LEVEL without any warning of the validity of the level and in spite of the fact that it is an argument option.

remake+ddd, can't see anything in ddd's source window

Hi there,

I've installed remake 3.82+dbg0.9 and ddd 3.3.12.

I've followed the steps on this page:
http://sourceforge.net/apps/mediawiki/bashdb/index.php?title=Remake_and_DDD

All the steps report back as expected ("--make invokes remake", running "remake --debugger -f" works fine from the console).

However, when it comes to the last step, "ddd --make Makefile", it runs ddd successfully, the bottom pane shows the remake console output, but the top pane (which ought to show the source) remains empty.

I can type remake commands just fine from the console (list, info, n, etc), but no source ever seems to get displayed in the top pane.

I'm running on opensuse12.3 linux (32-bit).

Build system should never require internet connection and download random packages. If dependencies are required, they either should be packaged alongside release, or clearly described (e.g. the build will fail in case GNU Readline is not available, but it won't try to download and install it on its own).

manpage has syntax error

Hi. There's a small syntax error in the manpage. Fixed here:

https://salsa.debian.org/debian/remake/-/blob/master/debian/patches/fixed-typo-in-manpage.patch

Does the argument debugger=preread work?

I am not sure if this is a bug or my misunderstanding of the docs, but...
The docs say "The “preread” sub-option enters the debugger after command-line options are parsed but before any Makefiles have been read."

But when I use "preread" I get this,

Is profiling working?

I download 4.2.1 and built on ubuntu 16.04
Then i pointed that to our makefile, the top level target, and asked it to profile; like so:

remake --profile -C dir/ -f Makefile all

The whole thing took one hour since we have too many targets to build. At the end of that I get a file called callgrind.out.193121
This is the entire contents of the callgrind file:

$ cat callgrind.out.193121
version: 1
creator: remake 4.2.1+dbg-1.4
cmd: remake --profile -C aris -f Makefile all
pid: 193121

desc: Trigger: Normal program termination
desc: Node: Targets

positions: line
events: 100usec
summary: 25644383

Am I missing something? Has Profiling been redefined?
Is Remake able to capture timings for all targets being invoked in the entire DAG for a makefile?

No remake for GNU make 4.0

Would you be interested in a PR updating remake to GNU make 4.0 and 4.1? (With suitable tags post facto)

i've searched for this feature but to no avail.
is it implemented?

Notice how readline's _rl_read_init_file() function in frame 1 ends up calling back into code supplied by remake. That's because both have a tilde_expand() function. The readline implementation never modifies the string passed in. The remake version modifies the string passed it, which can fail if a string literal is passed in.

remake's tilde_expand() has a signature:
char * tilde_expand (const char *name)

Hence it claims not to touch the string, but the error occurs during:
char *userend = strchr (name + 1, '/');
if (userend != 0)
*userend = '\0';

Here userend points into the name string. The const property gets dropped and the string is modified, breaking the signature's contract.

Workaround is to "touch ~/.inputrc" which cuts short readline's search for its rc file and avoids the bug.

A possible solution is to make remake's tidle_expand() have file scope using "static". However it's called from both read.c and main.c, so a bit of code reorganisation would be needed. Alternatively pick another function name that won't collide with libreadline.so.

One could also point out that if tilde_expand is not part of libreadline's public API, then it should have reduced the visibility of its symbols insulating itself for symbols in the parent executable that's linking in libreadline.

I'll supply a patch to rename remake's tilde_expand() if that helps.

I eventually got it to work by running, before make, cd doc && make stamp-vti, which I found in travis.yml.

I don't know if I was doing something wrong, but thought I'd give a heads up about this, in case other people run into the same issue.

Thanks!

New upstream, make 4.0

It totally lazy fashion I'm just going to ask if anyone has tried to rebase remake onto make 4.0.

Consider this as an intent-to-try, so if someone already is trying, speak up.

Breakpoints propogating to recursive make

If you set a breakpoint on a target but the same makefile is called recursively, you won't stop in at the target in the recursive call.

We could save a profile and change the recursive call to read the profile. That may also be a way to deal with issue #26

profiling options?

• set basename to use when creating profile data
• set directory to output profile directory
• a more compact format like CSV for output. Is there something other than callgrind that is more suitable?

Add remake --graph to show dependency graph

It would be very cool to be able to visualise all dependencies/prerequisites of a makefile. For example a ---graph switch which outputs a graphviz/dot file. There are a few perl scripts trying to do this but they fail for complex makefiles for me (which are the ones where it's needed the most). There is a make-profiler project which has this but unfortunately the project seems to be dormant so it would be cool if remake could adapt this feature (see https://github.com/eddyp/make-profiler).

archive test failures in remake 4.1-dbg1.1

Hi.

I'm seeing persistent test suite errors in the archive test. I'm at
remake-4.1+dbg-1.1:

 dima@shorty:~/debianstuff/remake/tests$ git describe --tags

Recipe:

1. autoreconf -f -i

2. ./configure --disable-nls

3. make

4. cd tests/; ./run_make_tests -make ../make features/archives

I can give you the differences, but first I'd like to confirm that this is

remake -xn isn't the same as remake -nx

remake -nx does perform a dry run; remake -xn does not.

The problem might seat between the keyboard and the chair, as I didn't extensively read the documentation (thus it could be intended behaviour, just unexpected for me); but I would expect them to perform the same.

System configuration

OS: Arch Linux
make: GNU Make 4.2.1
remake: GNU Make 4.2.1+dbg-1.4

Steps to reproduce

Example Makefile:

a:
	echo this was executed

Correct output

$ remake -nx
Reading makefiles...
Updating makefiles...
Updating goal targets...
 File 'a' does not exist.
Must remake target 'a'.
Makefile:2: target 'a' does not exist
##>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
echo this was executed
##<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Successfully remade target file 'a'.

$ remake --trace -n
Reading makefiles...
Updating makefiles...
Updating goal targets...
 File 'a' does not exist.
Must remake target 'a'.
Makefile:2: target 'a' does not exist
##>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
echo this was executed
##<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
Successfully remade target file 'a'.

$ remake -x
Reading makefiles...
Updating makefiles...
Updating goal targets...
 File 'a' does not exist.
Must remake target 'a'.
Makefile:2: target 'a' does not exist
##>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
echo this was executed
##<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
this was executed
Successfully remade target file 'a'.

Unexpected output

$ remake -xn
Makefile:2: target 'a' does not exist
##>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
echo this was executed
##<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
this was executed

targets without dependencies on them are "interesting"

There is a --tasks option which shows "interesting" targets. The targets for which there is no dependency on them, i.e. are the roots of the dag of dependencies, are also interesting.

Either these should be added to --tasks and/or an option/suboption provided show or include these.

Pragma-like comment to suppress --warn-undefined-variables

--warn-undefined-variables is really useful, but some modules are relying on undefined variables being empty, and they generate the checks in thousands. Not always they can be rewritten.
In this cases, it would be beneficial to have a pragma-like comment to suppress the warning for some of lines.
grep-ing them out would only help if the code testing the variable is not in $(eval).

Debugger: "data breakpoints": break when the command executed matches a certain regex

I have a huge set of makefiles.
I need to find what creates a certain directory.
I would like to set a breakpoint that triggers:

• when a command that matches .+mkdir.+problem_directory$ is executed.

The current breakpoints are useful when you know what file and line you want to stop at, but they cannot stop when a certain file is accessed.
